PILE-DRIVER..

SPECIFICATION forming part of Letters Patent No. 759,534, dated May 10,1904.

l l Application filed August 25, 1908. Serial No. 170,742. (No model.)

To all whom it warty concern.-

Be it known that I, EDWARD S..LI 1Ao1-I, a citizen of the United States,residing at Cooper Hill, in the county of Osage and State of Missouri,have invented certain new and useful Improvements in Pile-Drivers, ofwhich the following is a specification.

This invention has for its object to provide a novel construction ofpile-driver, the vital feature of the invention being to attain amachinein which the leader-frame may be adjusted so as to drive the posts orpiles into the ground at an angle or vertical. l he.derrickframe is alsopeculiarly mounted, being carried by a pivoted supporting-frame, whichis adapted to dispose the derrick-frame in variable positions relativeto thebody upon which the smpporting-frame is carried.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached. I

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention illustrated in the accompanying drawings, in which Figure 1 isa side elevation of a machine embodying the invention. Fig. 2 is a topplan view of the pile-driver. Fig. 3 is a front elevation. Fig. 4 is adetail perspective view, parts broken away, showing the peculiar mannerof supporting the derrick upon the pivotallym"ounted supporting-frame.Fig. 5 is a sectional view, parts broken away, taken through theadjacent parts shown in Fig. 4.

Corresponding and like parts are referred to in the followingdescription and. indicated. in all the views of the drawings by the samereference characters.

The main supporting-frame 1, which carries the derrick 2, is pivotallymounted, by means of a pivot 8, upon a truck-body 4, by which themachine is inoved from one place to another. The truck-body 4 may be thebody of a farm-wagon if the driver is intended for light work or acar-body should the driver be winch,

Y utilized for heavy work, such as driving large piles and the like. Thesupporting-frame 1 r is thus adapted to be rotated because of itspeculiar mounting to thereby dispose the derrick-frame 2 in any desireddirection relative to the truck 4. The derrick 2 is of ordinary type,generally speaking, and carries the leaders 5, which are suspended froma cross-bar 6 at the upper portion of the derrick-frame. The hammer 7 ismounted for shdable movement between the leaders 5 and is actuated bythe hammer-line 8, which passes around a roller 16, actuated by apulloyl? and connected by an operating-cable to the machine- Nippers 9,depending from the hammer-linc 8, cooperate with the 11001: 10 of thehammer 7 in the usual manner, being actuated to release the hammer bymeans of the cams 11, provided. upon the inner faces of the leaders. Thederrick 2 consists of spaced up rights having their lower ends passedthrough collars 12, swivelly disposed upon rigid arms l3, projectedupwardly from the supportingframe 1. The lower extremities of the saiduprights are received in sockets 14, alsodisposed upon the frame 1. Thepurpose of the peculiar mount of the derrick relative to the frame 1 isto adapt the former to be folded down upon the frame 1 when the machineis not being used or when the same is being moved from one place toanother. Brace-rods 15 are connected to the rear of the frame 1 and theupper portions of the derrick-uprights to brace the derrick structurewhen in operative position. Leaders 5 are provided with legs 18,slidably mounted in guides upon the lower portion of the said leaders,which are adapted to steady the position of the leader-frame by contactwith the ground. Bars 19 are likewise slidably mounted in guides uponthe sides of the supporting-frame 1, and these bars are also providedwith legs 20, which are adapted to prevent tilting of thesupporting-frame 1 in a manner which will be readily comprehended. Whenthe parts of the machine are out of use, supporting-legs 20 and 18 willbe moved in the guides in which they are supported in such a position asto lie flat with the other operating parts.

As before mentioned, the leaders 5 are pivotally secured to the derrick2, and thereby adapted for adjustment so as to drive vertical or at anangle. To fix the adjustment of the said leaders relative to thederrick, toothed bars 21 are pivotally connected to the leaders 5 andare provided with the toothed portions 21*, and these bars cooperatewith plates 22, carried by the supporting-frame 1, to fix the adjustmentof the leader-frame. To fold the derrick down upon the wagon, the. sameis given an upward movement to throw the lower extremities from thesockets 14, and then said derrick is given a pivotal movement to throwthe body thereof down upon the truck 4, the bars 15 and 21 beingdisconnected from the other operating elements to permit of the above.The supporting-frame 1 should of course be disposed in lines of thetruck 4 when the parts of the structure are in their folded positions,as above described.

Having thus described the invention, what is claimed as new is- '1. Inapile-driver, the combination with a supporting-body, a frame pivotallymounted upon the said body, arms projected upwardly from the frame,pivoted collars carried by the said arms, a derrick disposed upon theframe and comprising uprights having their lower ends received by thepivoted collars of the aforesaid arms whereby the derrick is adapted tofold down upon the supportingfralme, and leaders suspended from thederric I.

2. In a pile-driver, the combination with a supporting-body, a framepivotally mounted upon the body and provided with upwardlyprojectingarms, collars swivelly secured to the said arms, sockets rigidly appliedto the frame adjacent the said collars, a derrick comprising uprightshaving their lower ends passed through collars aforesaid and received bythe sockets for rigidly maintaining the derrick in a working position,and leaders suspended from the derrick and adapted for angularadjustment relative thereto.

3. In a pile-driver, the combination with a supporting-body, a framepivoted to the said body, arms upwardly projected from the said frame,collars swivelly secured to the said arms, sockets carried by the frameadjacent the said collars, a derrick comprising uprights having theirlower ends passed through the said collars and received by the sockets,leaders suspended from the derrick, and legs adjustably mounted relativeto the leaders to position same and legs carried by the supporting-frameto prevent tilting thereof.

4:. In a pile-driver, the combination with a supporting-body, a framepivoted thereto for movement approximately in the plane thereof, aderrick comprising spaced uprights, arms projected upwardly from theframe, collars swivelly mounted upon the said arms, sockets carried bythe frame to receive the lower end portions of the derrick-uprights, thelatter passing through the collar aforesaid, leaders suspended from thederrick and carrying the hammer, bars pivoted to the leaders aforesaidprovided with toothed portions for engagement with the pivoted frame tofix the angular adjustment of the leaders, and supporting-legs carriedby the leaders and the pivoted frame for rigidly maintaining the same inan operative position.

In testimony whereof I afliX my signature in presence of two witnesses.
